After some further Feedback, I implemented some Quality of Live changes. To have more time reading the Keys, the level now starts when the Player clicks on a button, also the first Trap  was to easy to overlook, so i added some (hopefully) mood inducing optical changes.

Complete Changelog:

• UI:
  • improved readable on brighter backgrounds
  • Display of Keys only vanishes after confirmation
  • Typo fixed
• Level
  • improved visibility of Trap

Some people would say, I procrastinate. Not developing the next Level(s). And they are not 100% wrong. But still got some preliminary logic and some first drawings how the next Level should look like. When there is some playable content I can upload, keep you posted.
